.SH "DESCRIPTION"
|
|
.B ibv_rate_to_mult()
|
|
converts the IB transmission rate enumeration
|
|
.I rate
|
|
to a multiple of 2.5 Gbit/sec (the base rate). For example, if
|
|
.I rate
|
|
is
|
|
.BR IBV_RATE_5_GBPS\fR,
|
|
the value 2 will be returned (5 Gbit/sec = 2 * 2.5 Gbit/sec).
|
|
.PP
|
|
.B mult_to_ibv_rate()
|
|
converts the multiplier value (of 2.5 Gbit/sec)
|
|
.I mult
|
|
to an IB transmission rate enumeration. For example, if
|
|
.I mult
|
|
is 2, the rate enumeration
|
|
.BR IBV_RATE_5_GBPS
|
|
will be returned.
|
|
.SH "RETURN VALUE"
|
|
.B
|
|
ibv_rate_to_mult()
|
|
returns the multiplier of the base rate 2.5 Gbit/sec.
|
|
.PP
|
|
.B mult_to_ibv_rate()
|
|
returns the enumeration representing the IB transmission rate.
